If you like it, by all means go for it. Folk are bigger nowadays than in the 1950s, and definitely better built than people in the 1930s. Wear a watch that complements your build. Personally, I would stay within 36-40mm, with occasional forays to 42mm in exceptional situations. The $$$$ watches tend to stay within a "conservative" size range because there are more people with $$$$ who are conservative than say, potential Hublot or Richard Mille buyers. What I find visually irksome is the 5'6" fellow with 6" wrists wearing a Big Pilot or that square Ball watch which looks like a cockpit instrument. Quite common nowadays. What I find mentally irksome is the 42mm watch with a big movement spacer within because the movement is a carryover from the 1960s/70s and the company took the easiest fastest cheapest way out. All style, no substance. Most irksome of all are the 42+mm watches with a generic ebauche that doesn't fit in terms of both size (too small) and shape (round movement in a square watch, c.f. aforementioned Ball).
